The relevant content involved in the embodiment of the present application is firstly introduced below.

1. About version 16 (Release 16, R16) search space group (Search Space Group, SSG) switching, or called search space set group (Search Space Set Group, SSSG) switching;

1. R16 search space group switching mechanism or technology: R16 introduces two search space groups (SS groups): search space group #0 and #1; and introduces implicit and explicit (supporting downlink control information DCI 2- 0 dynamic switching) two switching methods.

The network can configure one or more search spaces in the Type (type) 3-PDCCH CSS (common search space) set (set) or (or) a (one) USS (terminal specific search space) set to be associated with the search space group# 0 and/or search space group #1. The following search spaces are understood in the same way as search space sets, and will not be repeated here.

For example, the associated search space in search space group #0 includes all Type3-PDCCH CSS sets; the associated search space in search space group #1 includes all USS sets.

Then, if the terminal monitors the PDCCH on the search space group #1, or the terminal monitors the PDCCH on the search space group #1, it means that the terminal monitors the PDCCHs corresponding to all the search spaces associated with the search space group #1. The same understanding applies to search space group #0, so I won't repeat it here.

In addition, only Type3-PDCCH CSS set or a USS set is supported for search space group switching, and other types of search spaces do not support search space group switching. PDCCH on other search spaces.

The PDCCH monitoring behavior of the terminal corresponding to the application search space group #0 is: only monitor the PDCCH on the search space group #0, and stop the PDCCH monitoring on the search space groups other than the search space group #0.

That is to say, PDCCH monitoring can only be performed on one search space group at the same time.

The PDCCH monitoring behavior of the terminal corresponding to the application of the search space group #1 is: only monitor the PDCCH on the search space group #1, and stop the PDCCH monitoring on the search space groups other than the search space group #1.

searchSpaceSwitchTimer (R16 search space group switching timer timer): referred to as the first timer. The PDCCH monitoring behavior corresponding to the expiration of the first timer is: switching to the search space group #0, and then applying the terminal behavior corresponding to the search space group #0 (as above). Here, search space group #0 can be understood as a default search space group.

Only Type3-PDCCH CSS set or USS set can be linked (linked) to the above two search space groups, while CSS sets of other types (such as Type0, 0A, 1, 2, etc.) do not belong to any search space group, and do not It is applicable to the search space group switching mechanism, that is, the terminal will always monitor the PDCCH on it.

If there is an SS (search space) in the type3 CSS or USS that is not associated with these two search space groups, it also means that the terminal cannot skip the PDCCH monitoring on it through the search space group switching, that is, the terminal needs to monitor this The PDCCH corresponding to the search space.

2. Explicit search space group switching process (radio resource control RRC is equipped with DCI2-0-based related switching instructions), including:

Process 1: Trigger condition for switching from group (search space group) 1 to group0: DCI 2-0 is detected to indicate switching to group0.

Process 2: Trigger condition for switching from group0 to group1: DCI 2-0 is detected indicating to switch to group1 and restart or start the first timer.

Process 3: The trigger condition for switching from group1 to group0: the first timer times out, or the duration of COT (channel occupancy time) ends.

3. Implicit search space group switching process (under the premise that RRC is not equipped with DCI2-0 related switching instructions), including:

Process 1: Trigger condition for switching from group0 to group1: Any DCI format detected by the terminal on group0 will trigger the switching from group0→group1. In addition, if DCI of any format is detected on any group, the first timer must be restarted.

Process 2: The trigger condition for switching from group1 to group0: the first timer times out, or the COT duration ends.

Wherein: a UE (terminal) can configure up to 10 search spaces.

2. Regarding the R17 PDCCH monitoring adaptation scheme;

Specifically, it includes the following two sub-plans:

1. R17 (Release 17, version 17) search space group SSG switching, or R17 SSSG switching;

Different from R16 search space group switching, R17 search space group switching can configure up to 3 search space groups, namely search space groups #0, #1 and #2.

In addition, only Type3-PDCCH CSS set or a USS set is supported for search space group switching, and other types of search spaces do not support search space group switching. PDCCH on other search spaces.

The network may configure one or more search spaces in the Type3-PDCCH CSS set or a USS set to be associated with at least one of search space set #0, search space set #1, and search space set #2.

If the terminal monitors the PDCCH on the search space group #1, or the terminal monitors the PDCCH on the search space group #1, it means that the terminal monitors the PDCCHs corresponding to all the search spaces associated with the search space group #1. The same understanding applies to search space groups #0 and #2, and details will not be repeated here.

The PDCCH monitoring behavior of the terminal corresponding to the application search space group #0 is: only monitor the PDCCH on the search space group #0, and stop the PDCCH monitoring on the search space groups other than the search space group #0.

That is to say, PDCCH monitoring can only be performed on one search space group at the same time.

The PDCCH monitoring behavior of the terminal corresponding to the application of the search space group #1 is: only monitor the PDCCH on the search space group #1, and stop the PDCCH monitoring on the search space groups other than the search space group #1.

The PDCCH monitoring behavior of the terminal corresponding to the application of the search space group #2 is: only monitor the PDCCH on the search space group #2, and stop the PDCCH monitoring on the search space groups other than the search space group #2.

searchSpaceSwitchTimer-r17 (R17 search space group switching timer): referred to as the second timer. The PDCCH monitoring behavior of the terminal corresponding to the expiration of the second timer is: switching to the search space group #0, and then applying the terminal behavior corresponding to the search space group #0 (as above). Here, search space group #0 can be understood as a default search space group.

The specific switching process will not be introduced here. The difference from the R16 search space group switching process is that the explicit R17 search space group switching is through the specific DCI format of scheduling PDSCH (Physical Downlink Shared Channel) or PUSCH (Physical Uplink Shared Channel) (format) trigger, instead of explicitly indicating search space group switching according to DCI format 2-0 in R16 search space group switching. The specific DCI format may include: DCI format 0_1, and/or DCI format1_1, and/or DCI format 0_2, and/or DCI format 1_2.

The R17 search space group switching indication is used to instruct the terminal to switch to the target search space group, and the terminal performs corresponding PDCCH monitoring according to the PDCCH monitoring behavior corresponding to the application target search space group.

In addition, another difference is that the R17 search space group switching scheme has no implicit switching process, that is, there is no trigger mechanism similar to R16 implicit (that is, any DCI format detected by the terminal on group0 will trigger the switch from group0→group1) , the switching can only be triggered by explicitly indicating the above-mentioned DCI format 0-1, 1-1, 1-2 and/or 0-2, or the second timer expires.

2. R17 PDCCH skipping (skip);

PDCCH skipping is a method to achieve energy saving through the PDCCH skipping indication in the DCI indicating to skip the PDCCH monitoring for a period of time. For example, PDCCH skipping DCI is used to indicate to skip PDCCH monitoring in the following 4, 8 and 16 time slots. Skipping PDCCH monitoring means not monitoring the PDCCH. However, it should be noted that the PDCCH skipped for a period of time mentioned here refers to the first type of PDCCH, that is, the PDCCH corresponding to Type3-PDCCH CSS sets or USS sets. That is, only the PDCCH corresponding to Type3-PDCCH CSS sets or USS sets can be skipped.

The corresponding PDCCH monitoring behavior of the terminal within the duration of skipping PDCCH monitoring is: not performing PDCCH monitoring, or skipping PDCCH monitoring.

There are two types of terminal behaviors corresponding to the indication bits of the PDCCH skipping indication, one is that the bit value is all zero, and the corresponding terminal PDCCH monitoring behavior is not to skip PDCCH monitoring. Another type of bit value is not all zero, and the corresponding terminal behavior is to skip monitoring of the PDCCH (that is, the PDCCH corresponding to Type3-PDCCH CSS sets or USS sets) within a specific time interval.

3. About COT Channel Occupancy Time; before the 5G communication system transmits information in the unlicensed frequency band, on the unlicensed frequency band of New Radio (NR), before sending information, the terminal or network equipment needs to do Clear Channel Assess (CCA) or extended Clear Channel Assess (eCCA) to monitor the channel, that is, to perform energy detection (Energy Detection, ED). When the energy is lower than a certain threshold, the channel is judged as Empty, the transmission can start, that is, LBT (listen before talk). COT is the period of time occupied by the channel obtained after the successful LBT.

The channel monitoring method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings. In addition, the channels involved in the following may be specifically for the above-mentioned "first type of PDCCH" or other specific types of PDCCH, and will not be described in detail below.

The channel monitoring method provided in the embodiment of the present application, as shown in Figure 2, includes:

Step 21: The terminal obtains at least two kinds of channel monitoring information;

Step 22: The terminal performs operations related to PDCCH monitoring according to at least two kinds of channel monitoring information.

Wherein, the at least two kinds of channel monitoring information include at least two items of the following: PDCCH skipping information; channel occupancy time COT information; first-type search space group switching information; the first-type search space group switching information includes: first Search space group switching instruction information, at least one of the status information of the first type of search space group switching timer and configuration information related to the first type of search space group switching; the second type of search space group switching information; the second type The search space group switching information includes: at least one of the second type of search space group switching instruction information, the state information of the second type of search space group switching timer and the configuration information related to the second type of search space group switching; The state change information of the device; the state change information of the discontinuous reception DRX related timer.

Correspondingly, step 21 may specifically include: the terminal obtains the above-mentioned PDCCH skipping information, channel occupancy time COT information, first-type search space group switching information, second-type search space group switching information, and the state of the partial bandwidth inactivation timer Change information, and at least two items in the state change information of the discontinuous reception DRX related timer.

In addition, it is explained here that the at least two types of channel monitoring information acquired by the terminal may be acquired simultaneously or not at the same time. For example, "at least two types of channel monitoring information" are PDCCH skip information and COT information, then when the terminal acquires, The PDCCH skipping information and the COT information may be acquired simultaneously, or the PDCCH skipping information and the COT information may be acquired separately, for example: the PDCCH skipping information is firstly acquired, and then the COT information is acquired; but it is not limited thereto.

It is worth pointing out that step 21 does not limit the number of acquisitions of various channel monitoring information. For example, when at least two kinds of channel monitoring information include PDCCH skip information and channel occupancy time COT information, after the terminal obtains the COT information, it can PDCCH skipping information has been received one or more times. This embodiment only uses PDCCH skipping information and COT information as an example for description, and the number of acquisitions of other types of channel monitoring information is not limited.

The "PDCCH skip information" may include at least one item of PDCCH skip indication information and PDCCH skip related configuration information; the "status information" may include: status change information; the following default search space group may be based on "first It is obtained from at least one of the configuration information related to group switching of the search space class" or "configuration information related to group switching of the second type of search space".

The channel monitoring method provided in the embodiment of the present application obtains at least two types of channel monitoring information through the terminal; according to at least two types of channel monitoring information, performs operations related to physical downlink control channel PDCCH monitoring; can support the realization of multiple channel monitoring information The channel monitoring can clarify the relevant behavior of the UE to monitor the PDCCH, and improve the communication performance; it can well solve the problem in the prior art that the terminal cannot determine the monitoring behavior for multiple channel monitoring schemes.

In this embodiment of the present application, the search spaces associated with the first search space group and the second search space group are the same or different; wherein, the identifiers of the first search space group and the second search space group are the same, and the first The search space group is a search space group associated with the first type of search space group switching information, and the second search space group is a search space group associated with the second type of search space group switching information.

This can make the solution more flexible.

In the following, the case where the at least two kinds of channel monitoring information contain different information will be described respectively.

Optionally, when the at least two kinds of channel monitoring information include the PDCCH skipping information and the second type of search space group switching information,

The PDCCH skip information is not applied during activation of search space group #0 in the second type of search space group; and/or,

The PDCCH skip information is applied during activation of search space group #1 in the second type of search space group.

For example, the first type of search space group is a version 17 protocol (R17) search space group, and the second type of search space group is a version 16 protocol (R16) search space group. The terminal does not apply the PDCCH skipping information during the activation period of the R16 search space group #0 (that is, during the application period of the R16 search space group #0).

It can be understood that the fact that the terminal does not apply the PDCCH skipping information during the activation of the R16 search space group #0 means that the terminal during the activation of the R16 search space group #0: 1) does not perform PDCCH monitoring skipping, or, 2 ) indicates that the PDCCH skip indication information is not applied.

Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information,

The first type of search space group switching information is not applied during activation of search space group #0 in the second type of search space group; and/or,

The switching information of the first type of search space group is applied during activation of search space group #1 in the second type of search space group.

For example, the second type of search space group is a version 16 protocol (R16) search space group. The terminal does not apply the first type of search space group switching information during the activation period of the R16 search space group #0 (that is, during the application period of the R16 search space group #0).

It can be understood that the fact that the terminal does not apply the first type of search space group switching information during the activation of the R16 search space group #0 means that the terminal will not activate or apply the first type of search space during the activation of the R16 search space group #0 space group.

In another embodiment,

Optionally, when the at least two kinds of channel monitoring information include the PDCCH skipping information and the second type of search space group switching information,

The PDCCH skip information is not applied during activation of search space group #1 in the second type of search space group; and/or,

The PDCCH skip information is applied during activation of search space group #0 in the second type of search space group.

Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information,

The first type of search space group switching information is not applied during activation of search space group #1 in the second type of search space group; and/or,

The first type of search space group switching information is applied during activation of search space group #0 in the second type of search space group.

Optionally, when the at least two types of channel monitoring information include the first type of search space group switching information and the second type of search space group switching information, the terminal in the second type of search space During the activation of search space group #0 in the group, suspend or stop running the first-type search space group switching timer; wherein, the first-type search space group switching information includes: status information of the first-type search space group switching timer .

For example, the terminal suspends or stops running the R17 search space group switching timer during the activation of the R16 search space group #0. Further, during the period when the terminal exits the activation of R16 search space group #0 (that is, switches to R16 search space group #1), the R17 search space group switching timer resumes or starts running.

Optionally, in the case where the at least two types of channel monitoring information include: the first type of search space group switching information and the second type of search space group switching information, the terminal executes according to the at least two types of channel monitoring information Operations related to PDCCH monitoring, including:

The terminal monitors the PDCCH on the third search space, where the third search space is the search space group activated in the first type of search space group and/or the search space associated with the activated search space group in the second type of search space group ;

It can be understood that, in the activated R17 search space group and the activated R16 search space group, the terminal monitors the PDCCH on the search spaces of the intersection or union associated with the two activated search space groups.

For example, the activated R17 search space group is R17 search space group #2, and its associated search spaces are: search spaces #1, #3, #5; the activated R16 search space group is R16 search space group #1, and The associated search spaces are: search spaces #1, #2, #4. Then in an embodiment, the terminal monitors the PDCCH only in the search space #1 during the activation of the two search space groups. In another embodiment, the terminal monitors the PDCCH in the search spaces #1, #2, #3, #4, and #5 during the activation of the two search space groups.

Preferably, the specific condition includes: the length of skipping duration (corresponding to the length of the skipping PDCCH monitoring duration). For example, when the length of the skipping duration is less than the first time length, the above method 1 is applied, and/or, when the length of the skipping duration is greater than or equal to the first time length, the above method 2 is applied.

2. The configuration on the network side applies one of the above methods. For example, one of method 1, method 2 and method 3 is applied in network side configuration.

3. Terminal behavior:

(1) The UE PDCCH monitoring behavior corresponding to the R17 PDCCH skipping scheme applied inside the COT and outside the COT may be different. Corresponding to the above-mentioned PDCCH skipping information applied within the COT and the PDCCH skipping information applied outside the COT satisfy at least one of the following: the corresponding configured skipped PDCCH monitoring durations are different; the PDCCHs supported for skipping Different types.

1) Specifically, "different" may refer to different types of PDCCHs skipped within the skipping duration indicated by the PDCCH skipping. For example, the PDCCH types that can be skipped in the COT include the PDCCH corresponding to a specific type of search space, or the PDCCH corresponding to a specific DCI format, or the PDCCH corresponding to DCI scrambled by a specific RNTI (radio network temporary identifier), etc.; here No limit.

(2) Within the PDCCH skipping duration, the application priority of the applied terminal behavior of skipping PDCCH monitoring may be higher than the application priority of the R16 SSSG handover information. That is to say, within the PDCCH skipping duration, the terminal always follows the behavior of skipping PDCCH monitoring, and will not be affected by the R16 SSSG handover information.

For example, within the skipping duration, if an R16 SSSG switching instruction is received or if the R16 search space group switching timer expires, as shown in Figure 5, the terminal executes any of the following Option (options):

1) Option1: Switch to the target search space group according to the handover instruction or the expiration of the timer, but still follow the behavior of skipping PDCCH monitoring until the skipping duration ends, and then perform the corresponding PDCCH monitoring behavior on the target search space group. Corresponding to the above case where the terminal obtains the search space group switching information within the duration of skipping PDCCH monitoring, the terminal switches to the target search space group according to the search space group switching information, and in the PDCCH monitoring on the target search space group is performed at or after the end of the skip PDCCH monitoring duration.

2) Option2: Do not switch to the target search space group according to the switching instruction or the expiration of the timer, but wait until the skipping duration is over, then switch to the target search space group and perform corresponding PDCCH monitoring behavior on the target search space group . Corresponding to the above case where the terminal acquires the search space group switching information within the skipped PDCCH monitoring duration, the terminal, when the skipping PDCCH monitoring duration ends or after, according to the search The space group switching information switches to the target search space group.

(3) During the PDCCH skipping duration, the R16 SSSG handover timer is suspended, and the timer resumes operation after the skipping duration ends. Corresponding to the above-mentioned skipping PDCCH monitoring duration, the terminal suspends the operation of the search space group switching timer, and resumes the operation of the search space group switching timer when the skipping PDCCH monitoring duration ends or after .

(4) Within the PDCCH skipping duration, if the R16 SSSG switching instruction is received or if the R16 search space group switching timer expires, the terminal stops the PDCCH skipping duration, that is, stops the corresponding skip PDCCH monitoring behavior, and switches to the target The corresponding PDCCH monitoring behavior is performed on the search space group. Corresponding to the above-mentioned situation where the terminal obtains the search space group switching information within the duration of skipping PDCCH monitoring, the terminal stops performing skipping PDCCH monitoring, and switches to the target according to the search space group switching information A search space group, performing PDCCH monitoring on the target search space group.

(5) The network side can be configured to apply the above terminal behavior within the skipping duration if the R16 SSSG switching instruction is received or if the R16 search space group switching timer expires.

Part 2: Combination scheme of R17 SSSG switching and R16 SSSG switching (involving at least two kinds of channel monitoring information including the first type of search space group switching information and the COT information, and at least two kinds of channel monitoring information including the first In the case of one type of search space group switching information and the second type of search space group switching information);

1. This part includes at least one of the following:

1) Limit the application of the R17 SSSG handover scheme within the Channel Occupation Time (COT).

In addition: The R17 SSSG handover solution cannot be applied outside the COT, as shown in Figure 6.

2) The R17 SSSG handover scheme can be applied both outside the COT and within the COT.

2. Terminal behavior includes any of the following options:

(1) Option1: The R17 SSSG handover scheme and the R16 SSSG handover scheme cannot be applied at the same time;

1) Only one of the R17 SSSG switching scheme and the R16 SSSG switching scheme can be applied at the same time. It can also be understood as: the terminal applies one of the R16 SSSG switching indication or the R17 SSSG switching indication according to time sequence. Correspondingly, the terminal applies the target search space group switching information obtained at the current time, and stops applying the search space group switching information of a type different from the target search space group switching information obtained before the current time.

2) The switching instruction of R17 SSSG will rewrite (overwrite) the switching instruction of R16 SSSG, or the switching instruction of R16 SSSG will rewrite the switching instruction of R17 SSSG (also can be understood as switching information).

Further, if the terminal obtains the R16 SSSG handover information and the R17 SSSG handover information in the same slot, one of them is applied, or in the case of network configuration, the terminal applies one of them.

For example, during the application of the R16 SSSG switching instruction, if the terminal receives the R17 SSSG switching instruction or the state of the R17 search space group related timer changes (for example, the timer expires, the timer restarts, the timer is suspended, and the timer resumes), etc., the terminal stops R16 SSSG switching related monitoring behavior, and follow the R17 SSSG switching instruction and/or switch the timer state according to R17SSSG to monitor the corresponding PDCCH. Specifically, UE behavior is described as described in FIG. 7 .

(2) Option2: The R17 SSSG handover scheme and the R16 SSSG handover scheme can be applied simultaneously, but the following new UE behaviors are defined:

1) For a search space, when the terminal is triggered by the R17 SSSG handover information and the R16 SSSG handover information to monitor the search space, the UE can monitor the PDCCH on the search space (that is, monitor the PDCCH corresponding to the search space) PDCCH). For other search space groups, it is also confirmed whether to monitor the PDCCH corresponding to the search space group. Corresponding to monitoring the first target search space when the terminal determines to monitor the first target search space according to both the first-type search space group switching information and the second-type search space group switching information on the PDCCH.

For example, for the terminal-specific search space USS1, when the terminal receives the R16 SSSG handover instruction and performs PDCCH monitoring on the search space group associated with USS1, if the effective search space group in the current R17 SSSG handover mechanism is not associated with USS1, then The terminal does not monitor PDCCH on USS1 until the search space group associated with USS1 is applied in the R17 SSSG handover mechanism and the terminal R16 SSSG handover indicates that the search space group associated with USS1 is still valid, then the terminal starts to monitor the PDCCH on USS1, as shown in the figure 8.

2) For a search space, when the terminal is triggered by the R17 SSSG switching mechanism or the R16 SSSG switching mechanism to monitor the search space, the UE can monitor the PDCCH on the search space (that is, monitor the PDCCH corresponding to the search space). PDCCH). For other search space groups, it is also confirmed whether to monitor the PDCCH corresponding to the search space group. Corresponding to monitoring the first target search space when the terminal determines to monitor the first target search space according to any one of the first-type search space group switching information and the second-type search space group switching information on the PDCCH.

For example, for the terminal-specific search space USS1, when the terminal receives the R16 SSSG handover instruction to perform PDCCH monitoring on the search space group associated with USS1, the terminal starts to perform PDCCH monitoring on USS1, regardless of whether the association is applied in the current R17SSSG switching mechanism Search space group for USS1. The same is true for the R17 SSSG switching mechanism. As long as the search space group associated with USS1 is indicated, the terminal will monitor the PDCCH on USS1, regardless of which search space group is applied to the R16 SSSG switching mechanism, as shown in FIG. 9 .

(3) It can be configured by the network side to adopt any one or more UE behaviors in the above at least two UE behaviors (ie Option).

3. The network can configure the R16 SSSG handover scheme and the R17 SSSG handover scheme. The search space groups with the same search space group ID can be associated with different search spaces, and can also be restricted to be associated with the same search space. Correspondingly, the search spaces associated with the first search space group and the second search space group are the same or different.

For example, take an example in which search spaces with the same ID configured in the two schemes are associated with the same search space. The search space group 1 configured in the R16SSSG handover scheme is the same as the ID of the search space group 1 configured in the R17 SSSG handover scheme. If search space group 1 is associated with search spaces 5-7 in the R16 SSSG handover scheme, then search space group 1 also needs to be associated with search spaces 5-7 in the R17 SSSG handover scheme.

(2) Continue skipping duration, that is, continue to skip the PDCCH monitoring behavior on the switched target BWP. Correspondingly, the terminal continues to run the skipped PDCCH monitoring duration.

2. In the case of skipping duration and BWP inactivity timer starts or restarts, the terminal continues (runs) the current skipping duration. Correspondingly, the above terminal continues to run the skipped PDCCH monitoring duration.

Part 4: The R17 SSSG switching scheme is combined with the BWP timer (corresponding to the above at least two kinds of channel monitoring information including the first type of search space group switching information and the state change information of the partial bandwidth inactivation timer), the scheme includes at least one of the following one:

1. When the BWP inactivity timer expires, the terminal performs at least one of the following (corresponding to the first operation above):

As for which monitoring behavior should be followed, for example, an initial PDCCH monitoring behavior may be defined correspondingly after each BWP switchover, etc., which is not limited here. Specifically, the terminal may switch to the default search space group to perform corresponding monitoring behavior.

(2) Reset (or restart) the R17 search space group switching timer. Corresponding to restarting the first type of search space group switching timer described above.

(4) Do not restart (that is, continue to run) the R17 search space group switching timer. Corresponding to the above, the first type of search space group switching timer continues to run.

2. When the BWP inactivity timer is started or restarted, the terminal can continue to use the current search space group.

Part 5: The R17 PDCCH skipping scheme is combined with the DRX-related timer (corresponding to the above-mentioned at least two kinds of channel monitoring information including PDCCH skipping information and the state change information of the DRX-related timer), including at least one of the following:

1. Within the skipping duration, when the DRX timer expires or is started or restarted, continue (run) the skipping duration, that is, the terminal continues to skip PDCCH monitoring.

2. Within the skipping duration, when the DRX timer is started or restarted, stop the skippingduration, that is, the terminal stops skipping PDCCH monitoring. Corresponding to the foregoing terminal clearing the remaining skipped PDCCH monitoring duration.

Part 6: The R17 SSSG switching scheme is combined with the DRX-related timer (corresponding to the above-mentioned at least two kinds of channel monitoring information including the first type of search space group switching information and the state change information of the DRX-related timer), the scheme includes at least one of the following :

1. When the DRX timer is started or restarted, continue to apply the current search space group, that is, the terminal continues to monitor PDCCH on the current search space group;

2. When the DRX timer is started or restarted, switch to the default search space, and the terminal performs PDCCH monitoring on the default search space group.

3. When the DRX timer expires, continue to apply the current search space group, but the terminal does not perform the corresponding PDCCH monitoring operation on the current search space group, that is, does not perform PDCCH monitoring.

4. When the DRX timer expires, switch to the default search space group, but do not perform the corresponding PDCCH monitoring operation on the default search space group, that is, do not perform PDCCH monitoring.

In addition, the above-mentioned DRX timer (or DRX-related timer) includes: at least one of DRX onduration (duration) timer, DRX inactivity (inactivity) timer, DRX retransmission (retransmission) timer, and DRX RTT (round trip delay) timer.
